This computer-generated perspective view was created using data obtained from the High-Resolution Stereo Camera (HRSC) on ESA’s Mars Express. Centered at around 7°N and 353°E, this image has a ground resolution of about 26m per pixel. A part of Danielson crater dominates this view with the detailed relief of the yardangs being interrupted by the 19-mile-long (30 kilometers) field of dark dunes. The uniform thickness in the alternating sedimentary layers provides evidence for the theory that periodic changes in the climate of Mars occurred, possibly due to changes in the planet’s rotation axis.
